Ignore Matt's weird sense of humour, I do
The banned colour for Millennium this year is still yellow. The reason for that is that only yellow paint is allowed to be shot at a Millennium, so it makes sense to ban yellow on gear and clothing so that it reduces the amount of mistakes potentially made by a ref calling out a hit when it was in fact just a colour on your jersey or hopper.
The main difference with the CPPS is that our vendors at the CPPS sometimes also use orange paint (a previously banned colour). Therefore we advise that to have the least impact on your day and your games that you don't have any yellow or orange on your clothing or equipment. We don't strictly ban those colours, be we STRONGLY suggest that you don't. The last thing you need as a player is being pulled for a hopper shot when it's not. If you do decide to go with a piece of equipment or clothing which has any yellow or orange on it, then please just inform your ultimate before your day starts on field and where possible also let the other refs know. Just don't blame them if they do pull you for an incorrect call
Hope that makes sense! If you have any other questions, then please just message me
